Hi,

Value-Request is for your Input help(F4)

Help-Request is for your documentation (F1).

Cheers...

Hope the below info from documenation can throw some light for you. This is with addition to Event: AT SELECTION-SCREEN.

... ON VALUE-REQUEST FOR psel_low_high

Effect

In this addition, the field psel_low_high is either the name of a report parameter or of the form sel-LOW or sel-HIGH, where sel is the name of a selection criterion. The effect of this is twofold:

The possible entries pushbutton for F4 appears beside the appropriate field.

When the user activates this pushbutton or presses F4 for the field, the event is executed. You can thus implement a self-programmed possible entries routine for the input/output fields of the selection screen. If the program contains such an event and the user presses F4, the system processes this rather than displaying the check table or the fixed values of the Dictionary field - even if the report parameter or the selection option with LIKE or FOR points to a Dictionary field. You can, for example, use the CALL SCREEN statement to display a selection list of possible values. The contents of the field psel_low_high at the end of this processing block are copied to the appropriate input/output field.

This addition is only allowed with report-specific parameters (PARAMETERS) or selection options (SELECT-OPTIONS). For database-specific parameters or selection options, you can achieve the same effect by using the addition VALUE-REQUEST FOR ... with the key word PARAMETERS or SELECT-OPTIONS in the include DBxyzSEL (where xyz = name of logical database). In this case, you must program the possible entries in the database program SAPDBxyz.

Kind Regards

Eswar

F1 help is the documentation seen by the user for a field.
